DVLA (Driver and Vehicle Licensing Agency), an administrative agency of the Department for Transport, looks after registers of drivers and vehicles in Great Britain. This information helps DVLA improve road safety, reduce vehicle related crime, support environmental initiatives and limit vehicle tax evasion.

The DVLA is considering launching an inquiry after a peer said he tracked down "litter louts" with help from "friends" at the organisation. Lord Selsdon says he jots down the registration number of drivers he sees throwing litter from their cars and then tries to get hold of their phone number to tell them off. Find out more at BBC News.
